STORAGE TANK PRE-FILL & SANITIZATION
Pre-filling storage tank is required to both provide adequate pressure to check for system leaks and generate
water for flushing carbon post-filter. It is important to use provided sanitizer during Storage Tank pre-filling procedure.
1.
Locate vial of sanitizing granules. Open vial and pour contents into tank opening.
(Do not remove black Tank Cap)
2.
Apply 3-4 wraps of Teflon
®
tape (provided) to tank threads and thread Tank Ball Valve (included in sanitization kit)
onto tank.
***
WARNING: OVERTIGHTENING WILL CAUSE TANK BALL VALVE TO CRACK***
3.
Disconnect 3/8” yellow tubing from back of RO Purification assembly and connect one end into Tank Ball Valve.
4.
Connect opposite end of 3/8” yellow tubing to 3/8” x 1/4” Reducing Union (also included in tank sanitization kit).
5.
Connect free end of 1/4” orange “FEED” tubing to 1/4” side of 3/8” x 1/4” Reducing Union.
6.
With Tank Ball Valve open, open In-line Ball Valve and allow tank to fill (tank will fill in about 3 minutes).
7.
After filling tank, close In-line Ball Valve and Tank Ball Valve. Disconnect 1/4” orange tubing from Reducing Union . Set
tank aside for 15 minutes to sanitize. Leave 3/8” yellow tubing attached to both Reducing Union and Tank Ball Valve
while proceding with installation.
NOTE:
After performing pre-filling procedure, yellow Tank Tube will become pressurized with no means of pressure
release. If pressurized tubing becomes too difficult to remove from Reducing Union after procedure, close Tank
Ball Valve and cut off yellow tubing 1” from Tank Ball Valve. Remove and discard small fragment of tubing.
(Refer to Page 14, Figure 9 for more information on tubing removal from fittings)
IMPORTANT:
Retain 3/8” x 1/4” Reducing Union for future use in dispenser & tubing sanitization.
